To all 7172 0277. it may concern: a

Be it known that I, FRAXKWILL Von EL- ncurz. a citizen of the United States, residing wheels of motor cars, and more particularly the structure and mounting of the wheel hub and the pivotal. connection between the steering axle and the stub axle which carries the wheel.

The present invention has for its object to provide a hub structure of novel and improved form as will be pointed out and claimed hereinafter, and, furthermore, to provide a pivotal connection between the steering axle and the stub axle which Will give the wheel a caster action, thereby pre venting or minimizing the tendency of the car to skid or overturn in case the steering connection should be broken.

The invention also has for its object to provide a pivotal connection between the steering axle and the stub axle which gives the wheel an inward tilt at the bottom, and thereby counteracts the, tendency of the wheels to spread.

With the objects stated above in view, the invention consists in a combination and arrangemcnt of parts to be hereinafter de-' scribed and claimed, andin order that the same may be better understood, reference is had to the accompanying drawings, in which- I Figure 1 is a vertical section of the hub portion of the wheel and the parts associated therewith; I

Fig. 2 is a cross-section on the line 22 of Fig. 1; i

Fig. 3 is a cross-section on the line 3-3 of Fig. 1, and

Fig. 4 is a horizontal section on the line 44 of Fig. 2.

Referring specifically to the drawings, 5 denotes one end of the front or steering axle,

said end terminating in a knuckle 8 through which passes the pivot pin 10 whereby the connection with a stub axle 6 is made. The construction atthe other end of. the axle 5 is, of'course, the same.

' the stub axle 6 has a horizontal recess 7 to The inner end of accommodate the :nuckle 8, the width of the recess being" sufficient to allow the stub axle to swing sidewise, the pivot pin 10 be ing vertical. The knuckle 8 is slightly re duced at the top and bottom, as'indicated at 8, to take sleeves 9. The pivot pin 10 projects at both ends from the knuckle and has its projecting ends seating in the sleeves 9. The stub axle 6 has alined bearing apertures 11 in which the sleevesS are journaled, these apertures being in the top and bottom walls of the recess 7.

The stub axle 6 has two projecting cars 12 and 13, respectively, at its inner end, the,

same being in vertical alinemcnt and on opposite sides, or above and below the axle 5. The car 12 is provided for connection of the usual steering arm 14, the latter having a ball connection 15 with the steering gear link. (not shown), as is the usual practice. The car 13 takes an arm 16 to which is connected the cross rod 17 making connection with the stub action on the other end of the axle 5, and usually located to the rear of the letter. i

The stub axle 6 is encircled bye double ball bearing; 18, the races of which are made in two concentrlc sections, the inner section 18* encircling the periphery of the stub axle, and the outer section 18 seating in the hub of the wheel which is mounted on the stub axle.

The hub of the wheel comprises an. outermember 24 and an inner member 19. The two hub members have marginal flangesibetween which the spokes 26 of the wheel are clamped and secured by cross bolts 27. The flange ofthe outer member is shown at 24 and the flange of the inner member at20.

The inner hub member 19 has an inturned annular flange 19* which encircles the stub axle 6 in spaced relation and in which seats the outer section 18 of the ball races of the bearing'18. The flange has a ridge 21 which spaces the ball provided for adjusting the :ball races. said nut being screwed on a reduced threaded portion 22 of the stub axle 6 at the outer end thereof. A cross pin 23 is passed through the parts 21 and 22 to secure the same after the adjustment has beenmade. The outer hub finember 24 is shaped to form races 18". A cap nut 21*" is l a cap which closes over the outer end of v
